As we said recently, Cyanogen team has just released the first nightly of CM 10.1 with Android 4.2 for the Samsung Galaxy S3 in this tutorial we will see the steps to apply this update.

Those users who are using Samsung stock firmwares must obtain root access and install ClockworkMod on their Galaxy S3 to proceed with the installation.

If you do not know what is CyanogenMod (in case there is any off guard) I tell him that is a custom ROM developed by a dedicated and very talented group that seeks to bring the greatest possible Android experience to a long list of devices. This means removing the layers that are installed by default of manufacturers such as Samsung with TouchWiz, that while in the S3 does not go too slow it does bring things that fill our device with “garbage”.

Update Samsung Galaxy S3 to Android 4.2 (Cyanogenmod 10.1)

If you are a user of CyanogenMod 10 the upgrade process will be very simple for you, because since this version includes an OTA update application known as CM Updater.

Note: i´ve tried this process but did not work for me because the google apps crashed so I had to do a wipe data/factory reset and then install the gapps package of android 4.2 Jelly Bean. That way worked, so I recommend you do the same.

Update from CM 10

In this way System Settings> About Phone> CyanogenMod Updates> push the button located in the upper right corner, and select the updates option types incl. nightlies.

Then you have to select the last nighlty from the list and press on the icon on the right to download. When the download is complete you will see a message that says Apply Update and go!

Update from Stock Firmware

1 – The first thing we do is get root access and install ClockworkMod Recovery on our device, which you can do by following this simple tutorial

2 – Then we have to download the ROM from CM 10.1 from here (you can look out what is the latest on this link) and Google Apps package from here

After downloading the files will be moved to the root of the device, You will have to connect the Samsung Galaxy S3 to the PC via the USB cable.

After downloading the files, if you did it in the cell you must move them to the root of the device, it’ll need a file manager application, here is the link of some that I consider appropriate, they are all free with their links to Google Play:

3 – What we do then is start our device in recovery mode, for which we will (with the device off) press and hold the Volume UP + HOME + POWER, you can see how it’s done in the following tutorial:

Once in recovery we will move within the menu with the volume buttons to slide up and down and will select with the POWER button.

4 – The first thing to do is select “wipe data / factory reset“, we enter with the POWER button and select “YES – delete all user data” with the same button. Remember that for selecting this option you must go down with the VOLUME DOWN and VOLUME UP buttons.

5 – After a few minutes the process will complete, as in the previous step will do the same but with the option “wipe cache partition“, and select “YES – Wipe Cache” with the help of the volume buttons and entering with POWER.

6 – Then, also from the Recovery will enter in “advanced” and in this menu enter “Wipe Dalvik Cache“, as in the previous steps select “YES – Wipe Dalvik Cache” with the POWER button again.

Here’s a video and a post that explains how and what each one does, rest assured that you will not do any damage to your device (is in the Galaxy S3 but the processes are the same):

7 – Once you’ve done all three processes, without moving from the Recovery go to “install zip from sdcard” -> “choose zip from internal sdcard” and here will select the file “cm-10.1-20121218-NIGHTLY-i9100.zip” you downloaded previously and install it by selecting “Yes – install cm-10.1-20121218-NIGHTLY-i9100.zip” (will find it beneath everything along with the google apps package).

Note: if you have moved the files to the external SD should select “install zip from sdcard” -> “choose zip from sd card” (we decided to make the tutorial with the internal SD because all devices bring one with it, not the case of the external SD , but the process is the same and nothing will change)

8 – Once finished the process we will enter “install zip from sdcard” -> “choose zip from internal sdcard” and here will select the file “gapps-jb-20121212-signed.zip” which is the Google apps package and installed it by selectin “Yes – install gapps-jb-20121212-signed.zip“.

After completing these two installations will have to select “Reboot System Now” which is in first of the menus of the Recovery, if you’re not there select “+ + + + + Go Back + + + + +” until you find it.Ready! When you start your device you should see already the logo of CyanogenMod 10.1 indicating that the process was completed successfully!

Discussion

Adrian

I went through all the instructions, but when I reboot the phone into CM10.1, I get two error messages popping up continuously – “unfortunately, the process com.google.process.gapps has stopped.” and “unfortunately, Setup Wizard has stopped.”

The phone doesn’t seem to be able to get out of this loop. Any suggestions?
